Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a broadband mixer. Background Art

[0002] A mixer is a circuit that produces an output signal with a frequency equal to the sum, difference, or some other combination of the frequencies of its two input signals. A mixer typically consists of nonlinear components and a frequency-selective circuit. The mixer is located after the low-noise amplifier (LNA) and directly processes the RF signal after LNA amplification. To achieve this mixing function, the mixer also requires a local oscillator (LO) signal from a voltage-controlled oscillator (VCO). The circuit operates entirely within the RF band.

[0003] Existing broadband mixers are mostly fastened with screws during installation. When a broadband converter fails, it needs to be repaired or replaced. However, the current screw installation method requires the use of tools to tighten the screws every time it is installed or disassembled, which is time-consuming and labor-intensive, greatly delaying the repair and replacement of the mixer. In addition, the use of screws may cause thread slippage, which is not conducive to subsequent disassembly and use. Utility Model Content

A limiting block 12 is fixed to the sliding plate 11. The limiting block 12 passes through the connecting column 5, and the limiting block 12 is located above the connecting ear 3 to limit the broadband mixer body 1. By fixing the fixed base plate 4 in a specific position, and then using the provided connecting column 5 to insert into the connecting groove 7, and using the limiting block 12 protruding from the side of the connecting column 5 to prevent the connecting groove 7 from detaching from the connecting column 5, when removing, simply press the limiting block 12 into the active cavity 8, then the connecting groove 7 can be pulled out from the connecting column 5, and the broadband mixer body 1 can be removed.

[0021] Furthermore, a plurality of through mounting holes 6 are provided on the fixed base plate 4, and an expansion slot 14 is provided above the mounting holes 6. The provided mounting holes 6 are used to cooperate with screws to fix the fixed base plate 4 in a specific position.
